Standard tax rate for time recording items in the invoice

Hi,

Due to the e-invoice problem with various validators, I have switched from the invoice tax rate to the tax rate for product lines.
This is not a problem for products either, just enter the tax rate and it will be automatically applied when the invoice is issued.

However, if I invoice tasks, I have to set the tax rate manually.
Have I overlooked this option somewhere or is it simply missing?

My Workflow:

• The time recording runs “mostly” on a project, e.g. maintenance.
• An hourly rate is defined in the project, but no tax rate.
• Every maintenace i start a new time recording.
• The time recording does not allow a product selection but only a description.
• If I then invoice the recording, I simply mark it and select “Invoice task”
